HybridPower mode switching is now performed automatically. It can still be controlled manually via the Hybrid SLI control panel but for this tray icon to show up it needs special System BIOS support from the motherboard manufacturer. If supported please see instructions on manually switching HybridPower modes, please download the NVIDA Hybrid SLI User's Guide from the URL below:
